Stiebel Eltron Tempra 24 Plus Comprehensive Review

Stiebel Eltron Tempra 24 Plus Electric Tankless Whole House Water Heater, 240 V, 24 kW

Stiebel Eltron Tempra 24 Plus Electric Tankless Whole House Water Heater

  • Digital temperature control
  • Proven reliability
  • No venting required
  • Sleek design fits anywhere
  • Save at least 15-20% on the hot water portion of your electric bill

The Stiebel Eltron Tempra 24 Plus is a relatively new hot water heater that has been completely redesigned by the good folks down at Stiebel Eltron for a greater user experience. It comes with quite a few nifty features such as the digital temperature control and Advanced Flow Rate control, but it has trouble setting itself apart from it’s competitors.

The Tempra 24 is an electric whole-house water heater with a max GPM rate of 4.0. This sets it at about the middle of the pack in terms of flow rate and roughly giving you the power to provide two fixtures with hot water at once. It has Advanced Flow Control that is made to ensure a constant temperature output even if you are running multiple fixtures at once. It has a voltage of 240 and an amperage of 2 x 50.

The Advanced Flow Control is quite useful and seems to do it’s job well. The hot water that is outputted is at a very precise temperature and maintains that temperature throughout. The heater also comes with a digital temperature control that lets you set the temperature at whatever you desire, up to 140 degree Fahrenheit.

The Tempra 24 Plus’s design is high-quality and it looks to be very well-made.

Review

Stiebel Eltron claims that the Tempra Plus is “the most technologically advanced tankless water heater available on the market today”. I’m not sure if that’s true, or even what that really means, but they do seem to have put a lot of time and care into the redesign.

Users around the internet seem to enjoy this water heater and praise it for getting the job done – there aren’t any super fancy features that set it apart but there doesn’t really need to be for a good tankless water heater.

The Tempra 24 Plus gets high marks on accurate water temperature output and water flow. The Advanced Flow Control looks to be as good as advertised, nearly all users say their hot water was the proper temperature and that the temperature stayed consistent throughout the usage.

Some of the main drawbacks that come with this model seem to be involving the installation, especially the electrical installation. This little heater is a beast that needs a lot of power to get working, so remember that before purchasing. If you have an older house, especially, your electrical panel may be ill-equipped to output the energy necessary to power the Tempra 24, which requires two 60-amp circuits. New panels can sometimes be quite expensive, so make sure to look into what you currently have before making a purchase. Most users are reporting panel work will cost around $500, but of course that can vary wildly based on your set-up.

Once you get all these prerequisities into place though, you are set up for an enjoyable experience. The Tempra 24 Plus outputs unlimited hot water and at a precise temperature that rarely varies.

The Tempra 24 can easily handle 2 fixtures at once, such as running a dishwasher while also taking a shower. Any more than 2 may be pushing it, but you will just see a lighter water flow if you turn too many things on at once.

Pros
  • 3 Year Warranty
  • Precise Temperature Control
  • Good Water Flow
  • 99% Energy Efficiency
Cons
  • Additional Electrical Work May Be Needed
  • Slightly More Expensive Than Other Models
 Conclusion

The Tempra 24 Plus is a well-thought out, well0built tankless water heater that will satisfy all your needs, but may not give you anything special in return. The Advanced Flow Control is really nice and virtually guarantees your water stays flowing smoothly and at the precise temperature you set it to. The price is more expensive than other heaters, but you do get a quality crafted piece of machinery in return.

Can Tankless Water Heaters Keep Up With Demand

The concept of a Tankless Water Heater generated from the idea of creating hot water without the need to store it in a tank and waste energy constantly reheating the water. It is a push and get solution, turn on the tap and the water coming through the line nearly instantly converts into the given temperature. Hence, this saves gas and electricity energy immensely.

Every buyer is interested in finding out how tankless water heaters work and what is the mechanics behind a tankless system conforming to supply and demand of a household. Let’s unfold these basic and most frequently asked queries followed by some tips for choosing the right tankless water heater.

Tankless Water Heating System

There are multiple websites that have information about how tankless water heaters work. We would like to explain it here in the most simplistic and easy to understand manner that would solve all questions regarding tankless water heatings functions in one go-

  • Heat Exchangers Installed For Instant Hot Water

If you have a conventional water heater installed right now, take a look at it, it is holding certain amount of water, continually heating it a temperature that you would need for your next shower, say 2 hours from now. Heating water on an on-going basis for 2 hours until it is used, leads to wastage of energy.

To combat this wastage of gas or electricity, heat exchangers are installed in the tankless water heating system. As soon as a tap is turned on, water pulls from its source in its original temperature, the heat exchanger converts it into the desired hot temperature, and you instantly get hot water to your tap! The exchanger remains on standby the whole while, it activates only when water passes through the system. It is extremely user-friendly and easy to comprehend.

The exchanger is the main component to a tankless water heater and is what saves you money on energy, since it only activates when it is needed.

  • Point-Of-Use Or Whole-House Heating Solution According to Consumption

Tankless water heaters, thus, provide hot water through its electric coil or gas-fired burner (heat exchanger) which converts the temperature of water as it passes through. To meet the varying demands of consumption, tankless water heaters come in two categories- Point of Use and Whole House.

Point of Use water heating systems are for lesser usage, such as the kitchen tap or one other outlet at max. This category is handy, compact and easy to install. Due to it’s small size, it can be fixed anywhere near the kitchen tap which would reduce the lag time- interval between tap being turned on and water flowing. On the contrary, if more than two sources of water consumption need to be catered with higher consumption, Whole-House Tankless Water Heating Solutions are better.

Tankless Water Heating System Supply & Demand

From the many uses that Tankless Water Heating System comes in a household includes bathroom usage, hot tubs, washing machines for clothes, dishwashers and kitchen usage. Even if it is a nuclear family, but having 4 to 5 family members, chances are two or more people are going to need hot water at the same day during the day (don’t forget about showers, dishwashers, etc!).

Typically, most tankless water heating systems are designed to provide approximately 2 to 5 gallons of hot water per minute (GPM). This supply rate may definitely be sufficient for smaller family demands, but for larger ones, it is essential to either choose a gas lit water heater or install more than one water heaters.

For a greater understanding on how tankless water heaters supply hot water and which water heater would be the best to choose according to household needs, read the information given below.

  • Factors that Determine Supply Rate of Tankless Water Heaters According to Demand

The features in a tankless water heater that determine its capability of providing hot water include the size of the water heater that is being purchased, along with its fuel capacity and availability coupled with its cost. Opting for a sustainable fuel source such as gas instead of electricity would be better and environment friendly. As for the cost, the installation and buying budget that one has points out to the average GPM that is delivered by the water heating system.

Always check the GPM of the tankless water heater to understand its supply ability. Here’s a small example that would aid in the process of understanding how GPM works. For instance, the temperature of groundwater is 35 degrees, and the required temperature for a hot bath is 103 degrees, so the difference of 103-35= 68 degrees is the required rise that the Tankless Water Heater must be able to provide. Thus, choose at least a GPM converter that is suitable for a 68 degrees hike. If the GPM of a tankless water heater is 2.2 GPM and the shower head of the bathroom exits 5 GPM then it would be insufficient, even if the latest style shower head of 2.2 GPM is installed, the tankless water heater would be insufficient as it would mean that while hot water is being used in the bathroom it cannot be used in any other secondary source.

Therefore, one must be able to first calculate flow rate or amount of water that needs to be heated at one time and then compare it with the GPM offering of the Tankless Water Heater, this is the main source of making sure if the heating solution is capable of fulfilling demands of a household or not. For more detailed description of flow rate calculation per tap and room’s usage, visit http://home.howstuffworks.com/tankless-water-heater2.htm. Therefore, tankless water heaters are capable of fulfilling varying demands of a household, depending on which model has been chosen.

Saves Up on StandBy Loss

As mentioned earlier, the energy used in keeping water warm with a conventional water heater, the term used to explain the energy lost is standby loss since the water is not being used but simply waiting to be used. Tankless water heaters are famously known as the demand-type of water heaters. It basically means that it saves up on any standby loss that takes place with the conventional water heaters. Studies show that an almost 15% to 20% of energy is lost annually with conventional water heaters.

 

Benefits of Tax Rebates

Since using tankless water heaters promotes saving up on precious energy, most governments encourage home makers to adopt tankless water heaters by offering a tax credit. Although to benefit with this it is a compulsion to buy on those tankless water heaters that are certified to save up energy.

Some of the calculations posted by famous companies show that almost $80 can be saved up per year and $1700 in a lifetime on gas bills. Apart from that, depending on state laws specific credits on taxes are also enjoyed.

 

Lower Operating Costs

Where many people become shaky on the decision of buying tankless water heaters due to its high cost, when the resulting savings on energy, bills, taxes and operating costs is compared, the high buying price seems well worth it.

This customization accounts for saving up more on energy.

For instance, if a whole-house tankless water heating system is installed that caters to 5 faucets flow rate at a time, it would be of no use if a smaller family or two faucet flow rate is needed. By choosing the most suitable tankless water heater not only can buyers save up on additional buying price but energy can be saved up immensely as well.

 

Water Heating Bill Reduces

Environment friendly tankless water heating systems save up to 60% on gas bills. As these statistics have been quoted earlier by a different company as well, where up to $1700 can be saved in a lifetime, when it is seen collectively the sustainable energy is reduced in use by huge amounts.

This whole-house tankless water heater has a capacity of 9.4 GPM which clearly indicates that it is a solution for large families living together, or for those who need lots of fixtures running at one time. The

Rinnai RL94eN Natural Gas Tankless Water Heater, 9.4 Gallons Per Minute

Review

The Rinnai water heater was a vital backbone to my sister’s smooth wedding festivities. With over 3 families residing in our house during the occasion, we were in a fix as to how to accommodate water heating needs with our conventional water heater installed. It would simply end its hot water supply, and tough luck had it, it happened mostly during the middle of a shower.

We basically needed a water heating solution that was apt for providing instant hot water without much waiting, able to maintain its temperature when multiple outlets were on at the same time and alongside had to control electricity bills and gas consumption.

After receiving positive reviews and referrals for the Rinnai RL94eN tankless water heater, we finally invested in it and since then there is no looking back. Here is a brief insight of what pros and cons have become prominent since the time we’ve owned it.

Pros

  • Authorize for Federal Tax Credit- The Rinnai tankless water heater is energy efficient, and thus, qualifies for the Federal Tax Credit. This basically signifies that tax rebates can be enjoyed by owning a tankless water heater, it’s one of the initiatives that can lead to conserving sustainable energies such as electricity and gas.

 

  • Savings on Energy Bills- Reduction in energy bills up to a whooping 40%. Nevertheless, inflation has made it quite difficult to make ends meet and there are hardly many ways to save up and reduce costs. By installing the Rinnai RL94eN, an approximate 40% decrease in energy bills takes place, which is a decent contribution in itself.

 

  • Warranty Period- An impressive warranty period that safeguards the investment made on the tankless water heater. One of the best ways to differentiate average tankless water heaters with the best ones, is to compare the security via warranty. Rinnai offers a 12 years warranty on the heat exchanger, which is the most important part of the tankless water heater. Other than that, a 5 year warranty on its other parts and a 1 year warranty on labour installation costs, incase its placement needs to be changed.

 

  • Consistent Temperature of Water Supply- Rinnai delivers a consistent and non-fluctuating supply of hot water. Those who are used to conventional water heating systems or lower GPM tankless water heaters can feel the difference right away when no water related activity is interrupted due to shortage of hot water supply.

 

  • Touchpad for Temperature Changes- The model of tankless water heater sports a user friendly touch pad with a digital screen that makes water temperature adjustments quite easy. Some people had mentioned that the temperature change is not an easy task to do, but with the help of the manual adjustments in temperature can be done with ease.

 

Cons

  • Only Viable for Large Families- The water heating system is an excellent backup for large families, however, for a temporary usage like we had, soon the high capacity was of no use for us. The 5 plumbing outlet supply of hot water through the Rinnai tankless water heater is well worth paying for when majority of the times 4 or 5 plumbing outlets would be in use. Otherwise, cheaper alternatives are available in the market. However, for those who have to deal with seasonal usage of high capacity water heating solution, it is well worth spending the extra bucks since the warranty period and other benefits make it a pretty good deal.

 

  • Calibration Process is Lengthy- If the tankless water heating system loses power due to any given reason, the process of restarting it may seem confusing for someone who is not tech savvy and feels uneasy getting into its mechanics. Although, once the user guide is followed properly, a very simple step by step guide to the calibration process is given which ensures proper start up after emptying previous stored water from the heater.

 

Conclusion

There are many other tankless water heaters available in the market, but the goodwill and positive reputation enjoyed by Rinnai can be hardly found anywhere else. For families who need higher GPM and usage of hot water, this might be one of the best energy efficient solutions that is durable and backed up with an excellent warranty plan. This whole-house tankless water heating solution must be considered over other similar featured water heaters.
